New energy vehicle button battery 2032 represents cellular battery. What kind of black technology is it? As the core three-electric component of new energy vehicles, lithium batteries are directly related to important performance such as vehicle endurance, power, and safety. The cellular battery technology announced for the first time has attracted the attention of many industry insiders and new energy users. What exactly is cellular battery technology?

What kind of black technology is the "cellular battery" represented by the new energy vehicle button battery 2032?

Recently, there has been constant news in the new energy vehicle button battery 2032 industry. On the one hand, there is the strong announcement of blade batteries, on the other hand, the new announcement of sandwich structure battery packs, and on the other hand, the strong debut of honeycomb batteries, making power lithium batteries instantly become one of the most popular ones. The focus of people's attention.

The honeycomb battery is the latest achievement developed by JAC New Energy after 14 years of research and development. It is characterized by safety, all-weather availability, and higher energy. JAC new energy vehicles equipped with cellular batteries meet vehicle-level safety standards and can completely eliminate users' safety concerns. Honeycomb batteries use small-energy cells when selecting cells. Even if a single cell experiences thermal runaway, the lithium battery pack and the entire vehicle will not catch fire.

Honeycomb batteries are a new concept of lithium battery structure in addition to CATL's CTP technology, BYD's blade batteries, and sandwich structure battery packs. Reports of cellular batteries first appeared in March 2020. It is a button battery 2032 specially developed for new energy vehicles. Compared with general power lithium batteries, honeycomb batteries fully draw on the bionic design of the honeycomb structure. Using epitaxial coating UE technology for unit packaging, all cells in the lithium battery pack are 360-degree coated with lightweight self-leveling thermal conductive adhesive, creating a safe and comfortable home for each cell.

The cells of the honeycomb battery are arranged in a hexagonal shape, and the cells are filled with thermally conductive glue, which ensures the heat dissipation speed of the cells. 100% contact between the thermal paste and the battery core will speed up the heat dissipation of the battery core. The electrochemical reaction of the battery core inevitably causes heat dissipation, and the thermally conductive adhesive quickly transfers the heat to ensure that the temperature difference inside the battery pack is <3°C.

The cells of the honeycomb battery are filled with thermally conductive glue to achieve electrical and thermal isolation between lithium battery cells. If one battery cell fails, it will not affect the surrounding areas, so it will not cause a chain reaction.

The cellular battery uses NCA cylindrical lithium batteries supplied by Lishen Battery, which is also the supplier of TSLA Model 3 and Mercedes-Benz AMG hybrid models. Different from other models, iC5 does not choose soft-pack or square batteries, but chooses cylindrical lithium batteries, which makes the design of the battery pack require more stringent processes.

The design of the honeycomb battery makes the cell size small and the module structure flexible. It can make full use of the irregular space of the battery pack and obtain the maximum battery pack energy.

Compared with blade batteries, honeycomb batteries should not be underestimated. The new lithium battery structure concept has greatly improved the energy density of power lithium batteries, and the battery life has also increased by nearly 30% year-on-year. As a lithium iron phosphate battery, Representatives, blade batteries and honeycomb batteries have a very important impact on the counterattack of lithium iron phosphate batteries.

What are the advantages of cellular batteries?

1. In terms of its safety performance, honeycomb batteries adopt the design of multiple independent cells, which are combined through a honeycomb structure. Even if a certain cell experiences thermal runaway, this structure will prevent the entire battery pack from being damaged. Fire. Honeycomb batteries have undergone a number of rigorous tests. Directly heat with gasoline from the bottom and continue heating for 130 seconds; directly contact the battery pack with flame and continue burning for 130 seconds. In these extreme tests, the cellular batteries withstood.

2. In terms of battery life, the energy density of cellular batteries is higher than that of ordinary power lithium batteries, because the size of the overall battery cells is smaller and the module structure is more flexible. The combination of honeycomb structures has greatly improved The maximum energy of the battery pack and the heat exchange area of the battery core are more than 14 times that of other domestic products. The battery life has reached an unprecedented 530KM, which is an absolute leading position among the performance of many power lithium batteries.

3. In terms of the specific use climate, honeycomb batteries can be said to be available all-weather, similar to a honeycomb structure, which greatly reduces the energy attenuation of the battery core due to the influence of temperature. Similar to a beehive, it always maintains a suitable temperature for bees, which is conducive to optimal performance; the lithium battery heats up quickly when the temperature is low in winter, reducing the shrinkage of cruising range, and the battery cools down quickly when the temperature is high in summer, effectively extending the service life of the battery.

At the same time, the honeycomb battery has passed extreme safety verifications such as -40~80℃ temperature and humidity cycle, 130s fire, 200KN extrusion, and 1m water depth for 12h, and its performance is very good. button battery 2032 technology is changing with each passing day, and new technologies are emerging one after another. However, in the context of the general pursuit of energy density, cellular batteries that focus on improving safety technology obviously have more important significance.

Summary: Over the years, a major feature of the development of the lithium battery industry is that technology iteration is very fast. Initially, CATL launched CTP technology, followed by BYD's blade battery, and now JAC Motors has a cellular battery. The three lithium battery technologies are innovations and innovations at the application level. Who will win among the three lithium battery technologies? Let us look forward to it together!
